BELT Introduction Conveyor belts have been used for decades to transport bulk and unit loads. They have proved their worth everywhere because belt conveyor installations can be adapted to meet nearly all local conditions. They are work-safe and economical. The demand for ever increasing capacities and ever longer conveying lengths has accelerated the development of the belt conveyor technique, new materials are being developed, new conveying systems are being planned and tested especially those having regard to the environmental. The conveyor belt plays the major part in the whole system and has to overcome the many and varied stresses. In addition to this every conveying problem is different and needs careful planning and selection of the right elements in order to achieve the optimum conveying capacity in an economical way. There are a number of practical rules, values and experiences which can be useful during the planning stage. This manual aims to be of assistance to operators, engineers and project people and provides a substantial amount of elementary data. In addition there are a number of instructions and hints offered to enable accurate calculations or checks on installation components that impinge on the running of the belt. In future there will be more and more use of the computer for calculations and dimensioning of belt conveyors. With this often the correlation of the valuation criteria will no longer be recognizable. This manual should also help to understand the background to a calculation, the selection criteria for an optimum belt type and to recognize a special operating case. All new standards DIN, or ISO, have been taken into consideration as well as the results of individual research studies. The developments continue and we are grateful for all hints and practical experiences.

HISTOrY Until the mid 1970’s conveyor belt development and technology was concentrated on the search for appropriate materials for the belt and the solving of drive problems. In the first instance transmission of traction played a part. As the demand grew for conveyors of larger capacity and longer length, additional requirements effecting the belt had to be considered and researched such as greater work load, elongation, slit resistance and endless splice jointing. from 1870 Trials with plain cotton belts. up to 1914 First rubber conveyor belts developed from drive belts 1921 Founding of the Enerka factory. Manufacture of drive belts and later conveyor belts. 1923/1924 First use of belts underground, not a success due to drive problems. 1926 First belts with robust Balata reinforced covers. from 1928 Use of belts with Maco cotton plies. from 1933 Development of Rayon/cotton belts and pure rayon belts. Transition from natural rubber to synthetic rubber for protection of carcase. from 1939 Increased use of rayon and synthetic rubber. 1941/1942 Use of PVC belts above ground. 1942 Steelcord belts used for the first time for major long haul installations in the United States. from 1945 Further development of rayon belts. Introduction of mixed material fabrics includes synthetic weft. 1954/1955 Development of high tensile strength belts e.g. plies from rayon, polyamide and polyester. Cover rubbers with various surface designs. Steep incline belting with profiles and cleats. from 1955 Development and use of steel cord belting in Europe. from 1970 Use of Aramide as reinforcing material for the carcase from 1980 Development of new conveyor systems e.g. the tube conveyor, hammock conveyor.

This brief history illustrates the more important stages in conveyor belt development. The search for new materials became necessary because of the ever increasing demands to optimise installation construction such as pulley diameters, vertical and horizontal curves etc. and the demands of new conveying systems. • Optimising conveyor belt reinforcing materials i.e. exploit to their maximum strength limits to obtain optimum working life economy. • Optimum dimensioning of installation components e.g. pulley diameters, idlers, bearings and shafts, troughing transitions, drive and take-up systems. • Adaptation of cover quality to each duty i.e. cover quality to provide optimum solution at the most economical cost. • Manufacture of conveyor belts and installation construction with the environment in mind.

Importance of Conveyor Belts 6
Conveyor belts are referred to as belt conveyors and it involves endless loops of a material that are primarily used to transport objects from one location to another. Conveyor belts can be classified into two types 1] Curved Conveyor Belts 2] Straight Conveyor Belts A curved conveyor belt is curved in shape. In comparison to straight conveyor belts the curved conveyor belts in fact have various advantageous. Curved conveyor belts can run through any kind of curve, and most of the conveyor belts come with a curve shape of 45, 90, or 180 degrees. The belts are normally built in a flexible mode. These belts are mainly employed in agricultural and industrial purposes. Curved conveyor belts can be mostly segregated into vertical and horizontal conveyor belts. Vertical curved conveyor belts are more in demand. The vertical curved conveyor belts are held between two cases and are primarily employed for bulk material or unit carrying applications. Horizontal curved conveyor belts are usually built on the platform and are used for the carrying heavy materials. The functioning of a conveyor belt is pretty straightforward. In fact an array of conveyor belts are required for the proper working of conveyor belts. The essential part of conveyor belt tool is the splicing kit. Besides, heat measuring or controlling devices and different types of slitters form a central part of conveyor belt tools. Demand of Conveyor Belts in the International Markets China (Mainland), India, Pakistan, United States, United Kingdom, Iran, Australia, HongKong, Austria, Singapore

Objective Bulk material transportation requirement have continued to press the belt conveyor industry to carry higher tonnages over longer distance &more diverse routes .In order to keep up, significant technology advance have being required in the field of system desig , analysis and numerical simulation. The appilication of 8
traditional components in non traditional applications requiring horizontal curves & intermediate drives have changed & expanded belt conveyors possibilities. Examples of complex conveying applications along with numerical tools required to insure reliability & availability will be reviewed. As an engineering student our objective is to learn the practical/ actual design of conveyor system.
